JOHN BLAKE, OF LANGFORD, COLORADO.

DUMPlNG-WAGON.

SEEGIFICATION forming part of Letters Patent No. 684,174, dated October8, 1901.

Application filed September 1,1900. Renewed May 3, 1901. Serial No.58.654. (No model.)

To all wit/mt it nut-y concern.-

Be it known that 1, JOHN BLAKE, a citizen of the United States, residingat Langford, in the county of Boulder and State of Colorado, haveinvented certain new and useful Improvements in Dumping-VVagons; and Ido declare the following to be a full, clear, and exact description oftheinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings,

forming a part of this specification, in which similar letters ofreference indicate corresponding parts in both figures.

My invention relates to a class of dumpingwagons having four wheelsdesigned for hauling ore, bricks, or any material or substance that willpermit of unloading by careful dumping.

The object of my invention is to provide a dumping-wagon that can beunloaded with ease and without the usual sudden drop which makes so manydu mping-wagons impracticable, as the jar the wagon-box receives injuresthe contents thereof, or, if not the contents, injures the wagon itself.

I refer now to the drawings in further explaining the nature and objectsof my invention, in which- Figure 1 is an isometrical view of my deviceapplied to the bolsters of a wagon. Fig. 2 is an isometrical view of thebottom of a wagon-box provided with my invention.

A represents the front bolster of a wagon.

13 represents the rear bolster of the same.

0 0 represent two supports or beams, constructed of wood or othersuitable material, which are placed on and secured to the bolster, asshown in Fig. 1.

O O represent two bars or bands of iron, steel, or other suitable metal,which I secure to the front ends of the supports 0 C. These bars aredesigned for the rollers I and 1 which are secured to the bottom of thewagonboX, to roll upon when the wagon-box is being drawn backward todump.

D represents a crank-arm device which is secured to the supports 0 O bymeans of the lugs D and D and to this crank-arm is attached one end ofthe chain E, the other end being secured to the bottom of the wagon-boxII near the front end.

F represents the clutch device, which is provided with two clutch-hooksF and F and is secured to the supports 0 O by means of the lugs F and FA coiled spring F is provided which draws the device into position andlocks the clutch-hooks F and E into the eyes provided in the lugs F andF which are secured to the bottom of the wagon-box H.

G represents a rod or journal which passes through the rear ends of thesupports. The ends of the rod are secured into the standards of the rearbolster B. On this rod or journal are provided three cylindrical rollersG, G and G Two of these rollers come into contact with the plates orhands, of iron, steel, or other met-a1, designated by H- and H which aresecured to the bottom of the wagon-box H. Upon these rollers the boxrolls when being drawn backward to dump and when drawn forward intoplace. The roller G is designed to prevent the bottom of the wagon-box Hfrom sagging, as it is of larger diameter than the outside rollers G andG The wagon-box H is constructed in the ordinary manner ofany suitablematerial. The hooks (designated by H and H) which are secured to thebottom of the wagon-box are designed to prevent the box from being drawntoo far backward, as they catch on the rollers G and G The cross-support(designated by I) which is secured to the bottom of the wagon-box H hasa rod or journal running through it, the ends of which are secured intothe lugs, and placed upon the ends of the rod which passes through thecross-support I are two cylindrical rollers I and I hereinbeforereferred to.

It is now obvious that when my invention has been constructed accordingto the foregoing description and placed upon awagon the successfuloperation of the same will be as follows: By drawing out the clutchdevice F, which releases the clutch-hooks F and F from the lugs F and Fthe box is released, and the simple operation is to draw it toward therear by means of the crank-arm D, which winds the chain around thecrank-rod and pulls the wagon-box backward. As the box rolls upon thecylindrical rollers and the iron bars or plates, the movement of thesame requires very little exertion.

After the load has been dumped from the box the simple reversion of themovement of the crank-arm draws it back into place, when the clutchdevice F can be released, allowing the clutchhooks F and F to againsecure themselves into the lugs F and F which holds the box rigid uponthe wagon.

I do not confine myself to any one mode of constructing my device nor toany one mate rial, but desire to cover by Letters Patent the principleinvolved, making it in various sizes and varying. the mode ofconstruction and material used, as will be found most efficient andpracticable.

Having thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. In a self-dumping wagon of the class described, the combination ofthe front and rear bolsters, the supports or beams secured to thebolsters, the metal plates or bars placed upon the supports or beams atthe front ends, the crank-arm device secured to the supports on theunder side, the chain, one end of which is secured to the crank-armdevice and the other end secured to the wagon-box, the clutch devicewhich is secured to the supports on the under side by means of the lugsand is provided with two clutch-hooks designed to hook into the eyes ofthe lugs or suitable contrivances placed upon the bottom of thewagonbox, the coiled spring which adjusts and keeps in place the clutchdevice, the rod which passes through the rear ends of the supports, thecylindrical rollers which are placed upon the rod; with the wagon boxwhich is provided with two metal plates or bars designed to come intocontact with the rollers at the rear bolsters, the hooks which are alsosecured to the bottom of the Wagonbox and designed to catch on theoutside cylindrical rollers, the lugs having eyes to receive theclutch-hooks, the cross support-bar,

the two cylindrical rollers secured thereto designed to roll upon themetal plates or bars secured to the front ends of the supports or beams,substantially as specified.

2. In a self-dumping wagon of the class described, the combination ofthe bolsters A and B, the longitudinal supports or beams O, O which aresecured to the bolsters A and B,

the metal plates or bars 0 and C, secured to the upper side of thesupports or beams O, 0 near the front ends, the crank-arm dedeviceprovided with two clutch-hooks F and 7 F designed to hook into the eyesprovided in the lugs F and E, which are secured to the bottom of thewagon-box, the rod G, which passes through the ends of the supports 0, Cand is secured into the standards of the rear bolster B, the cylindricalrollers G, G and G which are placed upon the rod G; with the wagon-boxH, the metal plates or bars H and H secured to the bottom of the box H,the hooks H and H which are also secured to the box H, the lugs F and Fwhich are provided with eyes and secured to the bottom of the wagon-boxH, the cross support-bar I, and cylindrical rollers I and i attachedthereto, all as and for the uses and purposes herein fully set forth andsubstantially specified.

In testimony that I claim the foregoing as my own I hereunto subscribemy name in the presence of two witnesses.

. JOHN BLAKE.
